These are so airy and beautiful. They got to about 3.5 feet for me, then flopped over and blocked my garden path. I will keep planting this because it's an old favorite, though. So many blooms, and it's fun to guess which colors you'll get. They are one of the first flowers to succumb to cold weather in my zone 4.

I seeded in pots and planted late May in the garden. They grew nd grew all summer long. A beautiful green. I do grow them for the sparrows. I love to watch the tiny birds eat the seeds. I will be getting quite a show this year as the cosmos are a goo 4 feet tall and very showy. There are tons of blooms in all colors. As the rest of my garden winds down, these cosmos will bring fall beauty to me and food for my small birds. The bright spot in my garden as I pull the summer garden out. So bold and bright on these fall dreary days. Currently, we have a lot of smoke in the skies from catastrophic fires . The cosmos are the one bright spot in my garden. So thankful to have them.

I started these indoors in the spring and they've been blooming since late June. Very colorful, everything from white to purple to pink. My only issue is that the blooms don't keep well indoors, otherwise they're lovely and bring in many varieties of bees. Great for this amateur!

I think it must have been October before I saw the first blooms on these, so a bit disappointing in that respect. However, they were tremendous bloomers when they finally got started. I was so worried the buds would get zapped by frost before they opened! Fortunately, they were growing in a warm, sheltered spot, and I had several trick-or-treaters comment on the "pretty flowers" beside the front entryway, and they remained in full bloom up through Thanksgiving Day. It looked as though I had a fountain of flowers spilling over my front steps. I am not sure I will grow them again, though, due to the extreme late bloom aspect (and they do get huge--definitely best to plant these in the background. Come to think of it, maybe they'd be nice companions for Dahlia...).
